Perforating Approach Optimizes Proppant Distribution, Improves Well Performance

摘要

CANONSBURG, PA.-Reduced stage spacing has been demonstrated to improve well performance, but it also adds additional stages to a well, thereby increasing completion cost. The mechanics of why reduced stage spacing improves well performance are unclear, but observations from distributed acoustic sensing may shed light on one potential mechanism: a tendency for heel-ward bias in the treatment of a stage, where dominant clusters in the heel of a stage take the majority of the treatment, independent of the number of perforation clusters or cluster spacing.
